Mykel Williams

49ers coach Kyle Shanahan said tests confirmed rookie DL Mykel Williams has torn his ACL.

Fantasy Impact

It was the fear after Williams left Sunday's game early against the Giants with a knee injury. It is another season-ending injury at Metlife and another blow to the 49ers defensive line.

49ers head coach Kyle Shanahan stated Sunday that the team is concerned that Mykel Williams injured his ACL against the Giants.

Fantasy Impact

Williams is set to undergo more testing Monday. If Williams is out for an extended period of time, Sam Okuayinonu will likely see an increase in playing time at defensive end for the 49ers.

Mykel Williams was listed as an estimated participant on Monday's estimated practice report.

Fantasy Impact

Williams has taken on a bigger role with the injury to Nick Bosa. He should be good to go on Thursday against the Rams.

49ers defensive lineman Mykel Williams will miss "probably a week" with a knee injury sustained at Thursday practice, according to head coach Kyle Shanahan.

Fantasy Impact

Williams suffered what Shanahan said was "hopefully" just a hyperextended knee on Thursday, but he will undergo tests. The 11th overall pick of the 2025 draft is unlikely to suit up for Saturday's preseason opener against the Broncos.

Mykel Williams did not practice on Tuesday due to ankle injury.

Fantasy Impact

The 49ers are calling it a "minor" ankle injury for Williams. He can be considered as day-to-day.
